Patented May l, 1934 UNITED STATES PATENT oFFic PETROLEUM WICK BURNERApplication Nevember 9, 1929, serial No. 406,075 In Austria. November10, 1928 i claim. (ci. s- 94) This invention relates to petroleum wickburners for non-luminous ame of the type wherein a ame regulatorsurrounds the top end of the wick projecting out of a wick guide'andcarries 5 a combustion chamber enclosing the iiame. The name regulatoris provided with one or more apertures above which the flame burns,which dame is prevented by said flame regulator from striking back tothe portion of the wick between l@ said regulator and the wick guide.

1n arrangements hitherto known said iame regulator rests loosely uponthe top end of the wick and it is, therefore, diiiicult to secure acorrect position of the regulator Vrelatively to the i5 wick. When theregulator is in an incorrect position excess air may then pass into theame between the name regulator and the top end of Athe wick, therebycausing soot-bearing strips in the naine.l

im The invention has for its object to fix the anie regulator so that itacts as a stop :for the travel of the wick. By raising the wick, theupper end of the latter strikes against the name regulator held incorrect position whereby the top end of y the wick is enlarged and llscompletely the apertures of the regulator,v so that passing of anuncontrolled amount of excess air into the flame regulator is secured toa stationary part of 'the burner.

1 denotes the uppermost part of the fuel reservoir, 2 the round wick, 3and 4 guiding tubes 40 for the wick. 5 a. ring connected to the fuelreservoir, and 6 the flame regulator. The latter -is provided withapertures 6a which leave uncovered the top end of the wick and which areseparated from each other by bridge-pieces 6c, and air-supply apertures6b, provided in the side walls; 'la and '1b are the perforated jacketswhich are moimted upon the flame regulator and surround the combustionchamber. 8 is a protective casing releasably connected with the ring 5for sokeepingawaygustsofwindthiscasingbeingunitedwiththecasings'laand'lbintoaunitary whole, by means for example ofa. transverse rod passing through them. 'nietravelotthewickislmitedinthiscon- `|56 struction by a positioning nut Q,'whichcan be screwed upon a guiding pin l0 rigidly connected with the innerwick guiding tube by a bearing 11.

When turning the wick 2 up, its upper margin is pressed against theapertures 6a of the iiame regulator 6, and the latter is thereby pressedagainst the suitably adjusted positioning nut 9. The wick then fills theapertures 6a completely and bears against the bridge pieces 6c andagainst the walls of the iiame regulator bounding the apertures 6a. Inthis' way on the one hand the upward movement of the wick is limited,and on the other hand access of air through the apertures 6a isprevented. The apertures 6b, however, for the admission of air andpetroleum vapours into the combustion chamber remain free.

The air necessary for the complete combustion of the petroleum vapourspasses on the one hand through the inner air-supply pipe formed by thewick tube 3, through the perforated bottom of the name regulator andthrough the holes in the jacket 7a, and onthe other hand through thering 5 and the outer jacket '7b into the combustion chamber.

For ignition purposes the jackets 7a, 7b and 8 areA raised, and the wickis turned up until the edge of the wick presses against the apertures 6aof the flame regulator.

1 by the bent upper edge of the burner ring 5.

The name regulator 6 is provided with a perforated annular ange 6d whichsurrounds the latter and which strikes in its highest position against:said edge of the ring 5,`when the turned up wick has entered theflame-regulator 6 and has closed the holes 6a therein, the end of theWick being somewhat expanding in breadth.

The example of construction according to Fig. 3 shows a. fiat wickburner, the wick of which is surrounded by a flame regulator 6, whichunder its upper end, which is open and bridged over by bridge pieces 6c,has a constriction 6e, and under the latter the air-admission apertures6b, 106 through which the air necessary for combustion passes into thecombustion chamber surrounded by the perforated jacket '7 and to thename, whereas uncontrolledamounts of superfluous air which would causesooting of the flame are kept away by the wick bearing against theconstriction. Y

A perforated cap 6d forming one piece with the flame regulator 6 isprovided with an angle slot 6j, into which a pin 5a projecting inwardlyfrom the ring 5 is movable in the manner of a bayonet joint, therebyxing the flame regulator, In this case the ame regulator does not movewith the wick but is already secured in a denite position correspondingto the uppermost position of the wick during the-operation of theburner.

What I claim is:-

A petroleum wick burner, comprising a fuel container, a wick guid, awick projecting out of said guide, a flame regulator spaced from saidwickguide and having the form of a sleeve embracing and extending overthe top o! the wick and diverging downwards, said ame regulator havingapertures leaving uncovered the top end of the wick, and other aperturesarranged below the first named apertures and serving for the passage ofair and petroleum vapors developed from said wick, perforated wallsforming a combustion chamber arranged above said flame regulator,supporting means cooperating with the ame regulator for detachablyholding the ame regulator in a xed position with respect to the wickguide and container and the last mentioned apertures opening into thecombustion chamber.
